Fast dissipative collisions

Abstract At a bombarding energy of 14.7 MeV/u the charge, mass and angular distributions have been measured as a function of energy loss for reaction products induced by 98 Mo and 92 Mo projectiles on targets of 98 Mo, 147 Sm, 154 Sm and 92 Mo, 154 Sm, 238 U, respectively. An analysis of the product distributions shows the presence of a non-equilibrium sharing of the excitation energy, an exponential growth of the charge and mass variances, a complete N Z equilibration and a large yield of non-binary complex fragments. Monte Carlo simulations are found to be an indispensable tool of the analysis.
